[PATCH] sysctl: C99 convert arch/mips/lasat/sysctl.c and remove ABI breakage

While C99 converting the ctl_table initializers I realized that the binary
sysctl numbers were in conflict with the binary values under CTL_KERN.
Including CTL_KERN KERN_VERSION as used by glibc.  So I just removed the
sysctl binary interface for these values, as it was unsupportable.

Luckily these sysctl were inserted at the end of the sysctl list so this bug
was not visible to userspace.
